SPECIFICATION forming part of Letters latent in. 635,805, datedOctobrBl, 189p. Application filed November 28, 1898. Earls! No. 697,658. we model.) I i To all whom it may concern:

Be it known that I, JOHN POYSER, a subject of the- Queen of Great 'Britain, residing at Wirksworth, near Derby, England, have invented new and useful Improvements in or Connected with Battens for Weaving-Looms,

"Folding th'e'npperpart of the batten back or away from the fell of the'fabric, except when the said upper part is carried forward by the stroke of the lower part.

The object of this invention is to dispense with the spring and thereby obviate the strain and vibration caused by the action of the said spring when the lo'om' is working at a high.

' operating the two parts of the batten positiveiy in both directionsby means of oscillating or revolving cams, or I may use a single cam, which operates one part of f" batten, the other part being operated through the medium of a movable connecting piece or block having rollers, which extend into slots formed in the two parts of the batten, which slots are so shaped that when, say, the lower part of the batten is operated by the cam the slot therein will move thec'onpectihg-l piece, which wi ll in its turn act in the slot in the other part of the batten and move it in the desired manner.

Toenable my invention to befully understood,I-wil1 describe the same by reference to the accompanying drawings, in which-.-

Figure 1 is a longitudinal section of .part of a loom of the kind described in the specification before referred to and having the two parts of the batten driven by independent cams; and Fig. 2 is a section on the line 2 2 of Fig. 1, looking in the direction of the arrow 4 is a rear elevation, drawn to a largcr scale i 1 than Figs. 1 to 3, illustrating the arrangement wherein only one part of the batten is driven.

by a cam, the' other 'part being operated,

through the medium of a connectingiece. Fig. 5 is a side elevation of the same. 'Fig. 6 is a viewsimilar to Fig. 4, but showing the parts in a different position. Figs. 7 and 8 are side views of the upper and lower parts,. respectively, of the batten detached. Similar letters of reference indicate corresponding parts throughout the drawings.-

a is the lower part of the batten, which is fixed to the shaft 11, Figs. land 2, and oscillated from the cam c through the medium of I the arm 0', fixed to the shaft b and the rod (1 in the manner described in the specification before referred to, and e is the upper part of the batten, whichis-loosely mounted upon the shaft b and formedwith an arm f, as clearly shown in Fig. 3, to-which is connected one end of a rod g, the other end of which is. acted uponby a eanr'i on the main driving-shaft. Itwill be noticed by reference to Fig. 2 that the cams c 11 are in the. form of grooves, in. which rollersj j, near the lower 'ends' of the rods (1 9, run, the lower ends of the rods be-. ing bifureated,-so as-to embrace the drivingshaft, which thus fornis a guide'for the lower ends of the said rods; The cam-grooves e and 'i must be of such shape and arranged in such relation to'each other that the cam 0 will move forward the lower part of the batten until its dents coincide with those of the upper part,

which in the meantime has remained at rest, in order that the two parts of the batten may then move together from this position to beat up the weft laid in front of the batten and 0 then return-{the upper part c first coming to j rest and the lower part being then moved farther back to open the batten to allow the passage of the weft-finger of the shuttle for laying another weft, and-so on. 95,

In Figs. i to 8, which illustrate the arrangement wherein one part of the batten is positively driven from the other part through the medium of a eonnecting-pieee, k Z are the slots formed in the parts a and e of the batroo ten, respectively, and m is the connectingpiece, which is in the form of a lever or arm pivoted to. some suitable part of the frame ofthe machine and having at its freeend a pin a eseaos m, carrying two entifriotion-rollers o p in the slots is 1, respectively. These slots are of the some she. tension is which is concentric with the axis 5 of the shaft 1:. The slot lend the part of the slot k of similar shape coincide with one another when the two parts of the batten are eloeed together, as shown in Fig. 5, so that when motion is imparted to the batten part no a in a. backward direction-that is to say, in the direction 05 the arrow, Fig. 5--tlie pin n being acted upon by the slot It acts in turn upon the slot and causes the part c of the batten to move with the parts until the roller 15 1) reaches the upper end of the slot 1, when the motion of the batten pert e stops. As, however, by this time the extensionslot k in the batten pert a is opposite the rolier o the motion of the said batten pert acen continue ee its movement in order to form the opening between the two parts of thebstten, nssho'wn in Fig. 6. During the forward movement of the betten part a the movements are reversed-411st ie to say, the batten part a first except that the slot k has an exmoves independently and then the two parts 25 move together. I Having now particularly described and ascerteined the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 3o 1. 'A batten for looms formed of two parts having a common pivotal point with means for operating both parts positively to close them together, beat up the weft and again open them, substantially as described. 35 2. Abatt'en for looms composed of two parts, seid parts being positively operated, a cam for transmitting motion to one part of the said batten and e connecting-piece workin g in slots in the said two parts of the batten and eerv- 4o ing to transmit positive motion from the part operated by the cam to the other part, substantially as described.
